The sister's wide, hungry pussy aches for her brother's thick cock. She masturbates, her fingers plunging into her depths, squirts gushing out. He watches, jerking off, until she notices him. They argue, but their desire is palpable. Soon, they're naked, her pussy gaping, his cock hard and ready. She imagines him fucking her hard, stretching her wide, but their moment is cut short, leaving them desperate for completion.
